You don't mention what country you're in, which is confusing since you're a FB member but considering switching to a US carrier...
If you are in the US, I would strongly suggest the SPG Amex if you want to continue to transfer to FB and can put up with an Amex. You earn points at 1.25%. Another option to transfer to FB in the US is Diners Club, which is now a MasterCard. I'm not sure there are any other US-based FB transfer options.

If you want to switch airlines, deciding based on card processor is not a very good idea. You really should look into the airlines themselves first...

Sorry, but lack of blackouts are a feature of your airline's program, not of your credit card, when you're talking about transferring miles. And I'm not sure why you consider having a debit card worth listing as a criterion... Accumulation amount may be limited with airline affinity cards that have a tier system, but you generally get unlimited if you get the highest tier card (for a higher annual fee).
